Do I Need to Replace Brake Fluid When Changing Brake Discs?

[DeAugust]

Replacing brake discs does not require replacing brake fluid. Introduction to Brakes: Brakes, also known as braking systems, refer to the action of stopping or reducing the speed of moving locomotives, vehicles, other transportation tools, or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force. The braking device is a mechanical braking device that can slow down the speed, also known as a decelerator. Classification of Brakes: Drum brakes, advantages of drum brakes, disadvantages of drum brakes, disc brakes, etc.

When replacing brake discs, theoretically, there's no need to specifically change the brake fluid. However, based on my years of driving experience, I believe it's a good opportunity to check or renew the brake fluid. This is because when removing the caliper, air can enter the system, causing the brake pedal to feel soft or fail, requiring bleeding to remove air bubbles. If the brake fluid has been used for more than two or three years, it absorbs moisture and becomes dirty, which can corrode the pipes or affect response speed. Under high-temperature driving conditions, it may even boil and fail. For safety's sake, it's more reassuring to replace it during maintenance. I check the fluid quality every 20,000 kilometers and replace it if it's dirty. Don't risk saving a few bucks—it's too late when an accident happens. Remember to choose the correct type of fluid to ensure your car's brakes remain responsive and reliable.

As an enthusiast who frequently maintains my car, I believe it's best to handle the brake fluid when replacing brake discs. Brake fluid is crucial for the hydraulic system; as it ages and absorbs moisture, its boiling point decreases, accelerating wear. During the operation, removing the caliper might introduce air, requiring bleeding to restore performance. If the fluid is old, it's more thorough to replace it altogether. The cost isn't high, but it enhances safety and longevity. Don't risk bigger issues that could lead to more expensive repairs. I recommend checking the manual for the replacement cycle and combining it with maintenance for efficiency and peace of mind. Synchronizing these tasks during regular upkeep can prevent potential risks.

I've replaced brake discs myself a few times. While changing the brake fluid isn't mandatory, bleeding is necessary when air enters during caliper removal, and replacing the fluid becomes a convenient step during the process. If the fluid is dirty or has been used for years, replacement enhances safety by preventing brake failure due to lowered boiling points. The bleeding process is straightforward—just ensure you use the correct fluid type. Safety comes first; don't skimp on this expense.
